Foam cannons use less soap and water to wash your car. It’s more convenient to use a pressure washer to rinse your car after washing it with foam cannons than having to go back and forth with buckets of water. Less soap is also used because it will be mixed with the pressure washer, which improves conservation.

Another reason why using a cannon foam is necessary is it minimizes the time you spend on washing your car. Typically, it will take you a considerable amount of time to wash your car round with a car wash soap. You will have to make sure those dirt that is hidden in unreachable places is removed efficiently. With a foam cannon, you can spread soap towards all the sections of the vehicle by turning the pressure washer towards the direction.

If you have a dirty patio, porch or lawn, you can use the foam cannon as a quick solution to get rid of those dirt.

Types of Foam Cannons

Ideally, there are five types of foam cannons that are available in the market.

Adjustable Foam Cannon

This type of foam cannon can spray in different patterns. Hence, adjustable. It can be adjusted to spray in a stream pattern, single pattern, circular pattern, etc. Adjustable foam cannons make it easier for you to customize your spray pattern according to the part of the vehicle that you want to rinse. For example, single or direct stream allows you to focus on a targeted spot, while the fan or circular pattern works best at giving the entire vehicle a complete rinsing.

Quick Release Foam Cannon

The quick release foam cannon is more rampant in the market than the adjustable ones. This type of foam cannon has a ¼ – inch male fitting that is attached to the power washer wand. This makes the foam cannon to be more effective in rinsing and washing your vehicle. Also, you will be able to switch between washing and rising swiftly.

Professional Grade Foam Cannon

A foam cannon that is labelled “professional grade” is a high-quality foam cannon that is made of heavy-duty materials like stainless steel. This material is made to withstand wear and tear and offer increased durability and sturdiness. Professional grade foam cannon produces thicker foam, and are often expensive.

Foam Cannon Bottles

Foam cannon bottles are of two categories – opaque and transparent. If you enjoy watching the foam cannon work, you should forget about using opaque bottles. Opaque bottles won’t allow you to see the contents, but transparent bottles will. However, this won’t necessarily affect the performance of the foam cannon.

Foam Cannons with Interchangeable Nozzles

Sometimes, foam cannons come with interchangeable nozzle tips that discharges spray at different angles. For instance, foam cannons with interchangeable nozzles have common angles such as 15°, 25°, 40°, etc. These nozzles attaches to the end of the wand to help direct water flow.

What Can Cause Foam Cannons Not to Foam?

A lot of factors are responsible for your cannon not foaming efficiently. The type of pressure washer used, nozzle, type of soap used, etc. are common reasons why your foam cannon isn’t foamy.

Pressure washer

Sometimes, it’s not always about the foam cannon. Using a suitable water pressure determines how efficient the foams are. Electric pressure washers are quieter, easier to navigate around, and are smaller than the gas-powered pressure washers. It goes a long way delivering thick foam and ensuring that you have an excellent wash.

When it comes to power washers, two things come to mind – water flow rate and the PSI. Gas-powered pressure washers offer more PSI and GPM, and thus, are better in delivering thicker foam. Some foam cannons can handle 2 GPM and 1000 – 3000 PSI, while others can’t. You need to ensure that your power washer aligns with the foam cannon that you choose or have.

Car Wash Soap

While most soaps are designed to produce suds, there are others that create thicker foams. Some are engineered for use with a foam gun, while others aren’t. The type of soap used is crucial to how foamy the cannon would be.

Type of Water

Using cold water to mix with your foam cannon won’t produce enough foamy solution, and as such, shouldn’t be used. That’s why you should use warm water because it helps to aerate the soap and the mixture, so that thicker suds can be produced.

How to Make Foam Cannon More Foamy

These few trick will get the best out of your foam cannon to make it more foamy.

  1. Use the Ideal Power Washer

As we previously stated, using the right pressure washer is important. You need to make sure that the one you intend to use is compatible with the foam cannon in terms of PSI and GPM.

2. Make Sure You Use the Right Soap

Soap like watermelon snow foam, beer snow foam, etc. are special soaps that are designed to shoot thick foam and remove any debris or dirt on your car with some diluted water. There are other soaps that can shoot thick foams as well, so you should choose carefully.

3. Dilute the Soap With Warm Water

Most foam cannons use some advanced techniques to get the right mixture of soap, water, and air to shoot thick foam. In the dilution process, it’s important that you use warm water to ensure proper aeration of the soap and water mixture. This will result in shooting thick foam.

Once you have diluted the soap with water in the container, don’t shake the solution rigorously to avoid excessive buildup of the foam. Instead, swirl the solution in a circular motion.

4. Rinsing

If you are washing a car, make it a point of duty to always rinse the vehicle before you start to foam it. Doing this will take out the large dirt and debris at first before you can proceed to foam your car. Use a power washer to rinse the car thoroughly in and out.

5. Preserve Your Foam Cannon

Some people leave their foam cannons full of water and soap. This is dangerous as it will create calcium deposits that will prevent the cannon from shooting thick foam when next you use it.

After each use, ensure that you rinse your foam cannon thoroughly to avoid any calcium deposits. Empty the canister or bottle so that there is no leftover left. Thereafter, rinse the bottle with clean water. Reattach the canister to your foam cannon and shoot like you are spraying on something until there is no more soapy water coming out.

How Much PSI Does a Foam Cannon Need?

Typically, foam cannons require PSI between 1000 and 3000. You can use a light-duty to medium pressure washer to medium with PSI of 1400 – 2500. The type of pressure washer and the PSI is crucial. So make sure you check the specifications before using them with foam cannon.

What Is the Price of a Foam Cannon?

The price of foam cannons depend on a variety of factors. Most foam cannons are priced between $15 – $25. However, that is just the price of the foam cannon itself. When accessories like interchangeable nozzles and car wash soap products are added, the price could escalate to $60.

If you want a professional-grade foam cannon, it could cost you between $75 – $100. Reason for their expensiveness is due to the high-quality material that is used in designing them. Professional-grade cannons offer more dilution ratio and have better spray direction.
